Embodiment 1

[0022] A method for preparing metallurgical binder, comprising the steps of:

[0023] (1) Add SEBS elastomer, zinc oxide nanorod / mica composite powder, and epoxy castor oil to the mixed solution of methyl ethyl ketone and ethyl acetate, ultrasonically disperse for 20-30min, and add p-tert when heated to 60-80°C Butylcatechol and additives continue to stir and react for 40-60min;

[0024] (2) Continue to increase the temperature of the product of step (1) to 70-90°C, add rosin-modified phenolic resin, bisphenol A epoxy resin, thickener, and mix and stir at a high speed at 800-1000r / min for 1- 2h;

[0025] (3) Add the material prepared in step (2) to a grinder to grind and disperse evenly, filter to obtain a material with a fineness of 30-40 μm, and pack it;

[0026] Wherein, each component composition is counted as in parts by weight:

[0027] 33-38 parts of rosin modified phenolic resin, 3-5 parts of epoxy castor oil, 5-10 parts of SEBS elastomer, 5-10 parts of zinc oxide n...

Abstract

The invention belongs to the field of adhesives, and particularly relates to a preparation method of a metallurgical adhesive. The preparation method comprises the following steps of (1) adding an SEBS elastomer, ZnO nanorod / mica composite powders, and epoxidized castor oil in a mixed solution of methyl ethyl ketone and ethyl acetate, dispersing ultrasonically, heating, and adding p-tert-Butylcatechol and an additive, and continuously conducting stirring reaction; (2) continuously increasing the temperature of the product prepared in the step (1), adding rosin modified phenolic resin, bisphenol-A epoxy resin and a thickening agent, and conducting high-speed mixing and stirring reaction; and (3) adding the material, prepared in the step (2), in a grinding machine for grinding, dispersing uniformly, filtering to obtain a material of which the fineness is 30-40 [mu]m, and packing. The adhesive prepared according to the preparation method can prevent segregation or dust flying effectively and can improve the flowability of mixed powder. The preparation method is simple, low in cost, and low in environmental pollution, can realize large-scale production, and is suitable for various metallurgical processing fields.

Description

technical field [0001] The invention belongs to the field of adhesives, in particular to a method for preparing an adhesive for metallurgy. Background technique [0002] Metallurgical powder is fine mineral powder mixed with a small amount of binder, relying on capillary force and rotating mechanical force to form a ball powder with a diameter of 8-16mm, then dried on the roasting equipment, and recrystallized in a high-temperature oxidative atmosphere. Spherical raw materials with high grade, good strength and uniform particle size formed by bridge bond consolidation. [0003] Metallurgical binders generally include two categories: one is organic binders, and the other is inorganic binders. Due to the high price, low dosage, and difficulty in dispersion, organic binders have strict requirements on the pelletizing process. The main component of the inorganic binder is bentonite, and some use lime or other clay binders. During the use of adhesives, segregation or dusting i...
